Summary

Schizophrenia is considered the most debilitating and costly of all adult psychiatric illnesses. This chapter reviews current evidence-based treatments for schizophrenia and other severe mental illnesses with an emphasis on the effective components of each intervention. Evidence from dismantling studies is particularly useful in helping clinicians determine which parts or components of a treatment are most effective. Cognitive impairments in attention, memory, executive functioning, and processing speed are consistently found in schizophrenia, and some treatments aim to either restore these deficits to normal levels or provide strategies to compensate for these in the real world. Social skills training (SST) for schizophrenia has been used since the 1970s to provide patients with psychosis with the necessary skills to interact effectively with others. It has been consistently demonstrated that those with schizophrenia have impaired social skills that often predate the illness.
